iCloud Connectivity Issues

I'm hoping others may be able to assist me with diagnosing the cause of one of the issues with my Mac right now (without suggesting that I perform a re-install of my OS).

I have been noting issues within my Console log that I discovered when I was trying to verify why updates/additions I was performing in Reminders/Notes/Calendars were not syncing bi-directionally for any new entries done on the Mac, but updates from iOS would often come through on the OS X.

I have attempted various things including re-setting the hosts file back to the default one (and it is now effectively back in that state), I have disabled a 3rd party app-based firewall app called TCP Block and verified that OS X's Firewall is only blocking two applications (not Apple ones).

My iCloud account is actually a MobileMe account (with both an @icloud.com and @me.com email address associated).

Interestingly, I partially resolved some of my issues when I found that the Calendar application under OS X was returning 404 errors till I deleted external accounts I had linked to it and purged the Calendar Cache, but other iCloud related issues still persist.

My Machine is as follows: MacBook Pro Retina i7 2.8ghz, 16gb RAM, 512gb SSD and running OS X 10.8.5.

My console log is as follows:
